Fitts and Startts’ Law
Pierre Igot discovered that the click-through behavior in Snow Leopard’s Finder has progressed from unintuitive to batshit insane:
How is the user supposed to “know” and remember intuitively that click-through now only works in icon view mode and not in list view mode and column view mode? And how is the user supposed to “know” and remember intuitively that, even though click-through no longer works, “double-click-through” (to coin a phrase) still does?
There’s no question of users knowing any of this, of course, and certainly no question of them storing it in the muscle memory they use to deal with the core UI of their operating system.
I’ve long since given up trying to figure out how the Finder is going to react in any given situation, but this just rankles. In fact, I think it cries out for a new UI Law. Let’s call it Fitts and Startts’ Law:
Any sufficiently inconsistent UI behavior is indistinguishable from randomness.
Honestly, I wouldn’t be surprised if double-clicking a file in a background window caused a parade of flatulent spider monkeys to fart their way across my screen. That would be somewhat entertaining, at least, and no less unexpected than what actually happens.
